Formation

Lithium-ion cells are activated, packaged, and tested during the formation process. During this process, individual cells are charged to become EV batteries and tested for voltage, current, and cosmetic appearance. Completed EV cells are graded and tracked using barcodes before they are shipped to EV module and pack manufacturers. Cognex offers code reading, pouch surface inspection, cell stacking height measurement, and optical character recognition (OCR) solutions to help manufacturers ensure their lithium-ion cells can meet the demands of large-format battery pack manufacturers and energy storage system developers.
